The Prisoner's Dilemma is a fundamental problem in Game Theory, according to which players will not always cooperate with each other, even if it is in their interests.

John Nash believed transparency and openness are the qualities that lead to results beneficial to each participant in the game. From the other side, if there is no trust, the parties can stop to unfavourable decisions. Such situation has been since called Nash Equilibrium.
